Performance Summary
The Core i5-4590 + GeForce RTX 4090 pairing runs this title with CPU utilization between 60% and 100% and GPU utilization between 32% and 100%. Core i5-4590 reaches high load in heavier scenarios, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 53% at 1080p to 92% at 4K, while CPU averages move from 96% to 80%.
Load Interpretation
From a utilization perspective, this is a CPU-heavy load profile. At 1080p (Full HD) Low, the Core i5-4590 reaches 96% average load (92-100%), while the GeForce RTX 4090 remains comparatively lower at 47% (32-62%). This points to heavier CPU-side frame preparation work, but utilization alone does not define the FPS limiter.
Resolution Scaling
At 1080p, averages sit around CPU 96% and GPU 53%. At 1440p, that shifts to CPU 86% and GPU 74%, and at 4K it reaches CPU 80% and GPU 92%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
Optimal Settings Recommendation
4K (Ultra HD) High is the most balanced preset based on this dataset. It runs around CPU 80% (61-100%) and GPU 95% (90-100%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i5-4590 remains stable for consistent frame delivery.
Upgrade Insight
Both components are stressed near their limits in the heaviest presets (Core i5-4590: 96% avg, GeForce RTX 4090: 96% avg). A targeted upgrade should follow your target resolution: GPU first for higher image quality, CPU first for higher minimum FPS.
